z. State of hio. have invented certin new and useful liiiproveinents iii Heating Apparatus tor .itutonioliilesz and I do declare the following to he a iiull, clear,- and exact description of the invention. such as will en able others skilled iii th*y art to which it ap pertains to malte and use the same. l This invention relates to new and useful ,improvement-s in heating appail'atus t'orhautoiuobiles and Vother engine driven vehicles and the primary object of the invention isI to provide a device ot' this character which is adapted to utilize the exhaust of an `en-A gine for heatingr the automobile to add to" theconiicort of the passengers or Operator, l

particularly .during winter traveling.

Atiiothenobject of this invention is to provide a heater of this character, which is applicable to various types of autoiiiobiles,` hy a very simple operation, and owing to the simplified construction of this ty`pe of heater the same may he positioned either iii the floor ot' the autoniobile..or in an uprigrhtposition behind the :liront seat of the saine.

nother object ot the invention is to'pro- `vide a device of this character which is simple and durable in construction, inexpensive to manufacture, and one which will be very eiicient in operation.

`With these and numerous other objects in View my invention consists of the novel i features of construction` combination and arrangement of' parts which will be herein l inferred, to and more particularly pointed out in the specification and claims.

in describing my inventionv Il" shall refer to the drawings in which similar reference characters designate corresponding parts th oughout the several parts, in which Figs.

1 o tl illustrato the application of this type ot heater in. anupright position behind the front seat of an automobile while the relinaining figures of the `drawings illustrate this device applied in the floor ot' the inachine. l

rihe numeral 1 designates an upright holv 'with a plurality of transversely extending air tubes 3 which project therethrough at spaced intervals, as clearly shown inV Figs. 3, 4 and 5 ofJhe drawings.

The casing 'l is provided in one of its edges 4 with a notched portion 5, which has in the opposed faces 6 and fot' the saine an inlet opening 8, and an outlet opening i) that are positioned .substantially in alinenient with each other. Through the casiingr l between the corrugated side walls 2 ot' the saine is formed a tortuous pass ge lor the gases which discharge into the saine through the inlet 8 and said passage is .formed by partitions 10, that project f roin certain of the air tubes 3, and which are fully illustrated in Fig'. t of the drawings. By this uians the gases will upon entering the casing through the inlet 8 be directed through the tortuous passage foi-ined by the partitions, in such a inaunei' that they will circulate freely'withiii the casing7 during the passage therethroiurh. to the outlet 9, for the purpose ot which is obvious in devices of this` character.

A substantiallyU-shaped inlet pipe ll, has its inner end l2 positioned through the inlet 8 ot the face of the notch 5 and said end oi the pipe is surrounded adjacent the end 12 by a projecting ring 13, which when said pipe is in position is adapted-to lic flush against the outer surface ot' the tace (S. This pipe projects from-the notch and has its free end 13 connected. by e tubular member 14 with the exhaust pipe lll@ 15 of the enginefor the autompbile. 'Ifhe end`f the tubular member 14 that'is connected with the exhaust pipe is' outwardly flared to form a hood 16 whichsurrounds an opening 17 in said exhaust pipe and isA securely positioned thereon by a cllip 18.

Positioned Awithin the easing 1. is a valve 19, which'is adapted' to bepositioned over the inlet 8 of fthe same, and said valle has a stem 20 extending through the adjacent end of the casing as shown at 21, and provided "with a wheel 22 on its outer projecting end.

The portion of the 1 stem 20 projecting through the wall ot the end of the casing is threadedly engagedv therewith so that upon the rotation of the wheel 22,the valve 19 will 4 be moved into and out lof position over the -inlet 8 of said casing.

of its ends 24 projecting through the said' outlet openingin the wall of the notch. Ad-

' jacent the end 24 of the pipe is a projecting ring 25 surrounding the vsaine and adapted when the pipe is in position to engage the outer face 7 of the notch. in a manner similar to the connection employed at the end 12 of the inlet pipe. vThe outer end of the'outletvpipe 23 is connected with a tubular mutfler 26, intermediate its ends and said mufller is formed with projecting rotary ribs from the center of the same to its opposite ends,

' so that the exhaust gases discharged into the same `will consequently be sulliciently mutled during the passage therethrough. The

`last spiral of the rotary internal ribs within the mnfller is broken,r so that the outlets of the muiller will not be,- obstructed, and the gases may be easily discharged therefrom.

The outerportions ot' the inlet pipe' ll and the outlet pipe, 23 that are positioned between the opposed faces (i and 7 of the notch 5, have formed on their outer sui-,tace

cone-shaped sockets 37, and positioned in one of the soekets37 isa cone-shaped end 38 of" a bolt 39. This bolt is externally threaded' and is adapted to be operatively engaged by a nut 40, which has its outer end formed with a cone-shaped head 41 adapted to be positioned within the .other coneshaped socket 37. I Y pansible and contractiblemember is adapted to be positioned between vthe portions of the pipe disposed within thc notch so that when` -Athe innerends ot' the pipo have been insorted in the alining openings S and 9in tbc opposed faces ot said notch, upon theI dispoly this means an ex-` sition of this member betweenthe pipest, and the engagement of the cone-shaped ends of the same with the cone-shaped notches in the pipes. its expansion willsccurely drive the ends ot' the pipe in the openings and will force the rings adjacent said ends against the faces oi? the notch, thereby sccurcly holding saidpipes inposition. lVhen it is desiredto release the pipes, upon the operation of the nut 40 this member will be contracted, whereby the pressure being relieved from the ends of the pipes, the same may be easily withdrawn from the openings in which they are positioned.

The above described various elements of this type of heater are. common to the same when this device is used either in a horizonf tal position in the (loor'of the automobile, or whether it is positioned vertically and is disposed behind, the front Seat of the machine.

In the type of my device illustrated in Figs. 1 to 4 of the drawings and which shows the same in upright position, the casing is surrounded by a jacket 27, which is secured at its bottom to the floor of the car. through whichfloor openings in which the inlet and outlet pipes .may communicate with the casing are positioned. This jacket 27 is provided "through its outer side at 2S with a plurality ot' vair outlet openings 2S). while projecting laterally from the ends of the same and adjacent the bottom are air inlet pipes 30. These air inlet pipes are connected by flexible tubular members with the running board shields on opposite sides of the automobile and these members which areA designated `b v the numeral 31 project therethrough as shown `at 32, so that their outer' ery of the wheel' 22 are adapted to project.

The projecting portions of the wheel 22 are 'roughened. so that the wheel may be rotated when. it is desired to operatethe valve that controls the inlet to the easing.

llvhen the heater is usedin the Hooi-'ot the automobile, as illustrated in Figs. 7 -and S .of the drawings. l provide for the same a jacket or box 84 which is positioned below the floor ot' the car-and through an opening in the-same, andthe said box 34 hasan open top, over which is secured a perforated4 floor plate 35 on the floor of the'automobile. The box 34 is provided adjacent "its opposite ends with air inlet pipes 36 that. project therefrom .and are connected by flexible 'tubular members 3l which have their outer ends projecting through the running board munication between the jacket or box 34. and thel atmosphere so that fresh air will be continuall y fed to the same.

T he casing l is horizontally positioned .within the box or jacket 34, and said box lao hasI an opening through its lower side or bottom, through which the inlet. and outlet pipes l1 and'QS of the casing are adapted to project. Thus the exhaust gases from the engine may be fed to the casing in a manner hereinbeore more fully described. The wheel 22 that operates the valve that controls the inlet to the casing projectsv upwardly through the floor plate and has its projecting portions roughened sothat the wheel may be rotated when it is desired to operate the valve to control the flow of gases through the casing.

l4` rom the above description of the various elements of this heater that are common to the same when the heater is used either in horizontal or upright position, it will be obvious that theheater may be easily and simply applied to any type of automobile 'hind the front seat of an automobile, the

pipes are disposed in a single plane therewith and project from the same through a small opening in the licor ofthe car. lWhen the heater is positioned below the floor of the automobile, the pipes are positioned at right angles to the casing, so that they will. project downwardly through the bottom of the vjacket orboX injwhich the casing is posed. lt is onlynecessary in applying this type to position the jacket or box .through an .opening in the floor ofthe car withl the heater in Jgia-mea and' to apply the floor fp'lat'e over the said opening. The type ot'lconnection between the air inlets tothejlackets that surround the casing is similarin both forms as is clearly illustrated in the accom-,

panying drawings`- From the foregoiz'ig description of the construction and operation ot. this type of heater for motor vehicles. the construction and operation of the same -will be readily understood and it will be seen that l have provided a simple and elicient means;\for carrying out the objects of this invention, The object of the corrugated side walls 2 ot acket o-r box.

the casing l is to give a greater space for thel air to circulate over, so that the same will be thoroughly heated before it is dis-4 charged from the jacket. The passage of the air through the heating device is similar in both types of the device, namely, the said air is fed to the jacket through the inletv passages of the same vthat communicate with the atmosphere through the running board shields of the automobile and hence around the casing and out througl'i the perforated side wall ot the jacket, or if the heater is used in a. horizontal position. up through the 'floor plate which forms one side of the The projecting portion of the wheel 2Q that (aiperates the valve that controls the inlet to 4the casing projects through the wall of the jacket or through the floor plate so that the valve will always be within easy reach so that the heater may be quickly shut off or turned on when desired.
